Variability and structure variation morphological characteristics species Tulipa L. South Ural

The study of intra-and inter-population variability, patterns of variability of morphological characters Tulipa biebersteiniana, T. patens and T. riparia in the South Urals. In general, for the species is characterized by a high variability of the parameters of flight, low volatility - the parameters of the flower. Cluster analysis tcenopopuljatcij species based on morphological features of individuals in populations of species identified three groups. The first group included coenopopulations T. biebersteiniana of steppe and heavily grazed habitats. The second group included coenopopulations T. riparia of riparian habitats, and the third group consisted of steppe coenopopulations T. patens. Highlighted morphological features - the system indicators, which are manifested in the variability of adaptive responses of species.
